The company’s headquarters is the main platform. The INDeX provides a WAN
link to a regional office. Smaller sites use ISDN dial-in access and an Avaya IP
Office for access as and when required. Finally, staff on the move, such as the
sales team, can dial in from residential, hotel or mobile phones.
Many features support effective data service operation:
– Bandwidth-on-demand. Extra ISDN channels are automatically added (or
dropped) when data traffic reaches (or falls below) user-specified threshold
levels
– Password authentication
– Transparent WAN and ISDN operation between platforms.
The system RAS facility handles incoming calls from external users dialling in to
local services. Similarly, the Service facility manages calls to outside services.
Network Address Translation (NAT) provides simultaneous user-connectivity and
DHCP caters automatically for addressing on the local network, for both network
PCs and dial-in users.
There are also a number of security features for controlling access to data
services, see pages 22, 31 and 115.
